Save 15% on this smart padlock you unlock with your fingerprint (or a key)

I hate using public lockers -- you know, at the gym, the beach or a swimming pool --  because I either need to memorize a combination or end up carrying a key around and neurotically worry about losing it. Benjilock, a Shark Tank alumnus, has a better idea: Use a smart lock with a fingerprint reader. Right now, you can save 15% on either of Benjilock's models -- a 44mm padlock and a TSA-approved mini travel lock -- when you use discount code 15OFF at checkout. That's the lowest price we could find anywhere for these locks. 

Benjilock is technically now Benjilock By Hampton; Hampton scooped up the startup after it appeared on Shark Tank. The locks are currently featured at brick-and-mortar tech store B8ta. (Editor's note: CNET has partnered with B8ta for in-store and online events.)

Here are the two Benjilock models on sale right now.
